Data communication and networking are the backbone of the modern world. They allow us to connect with others, share information, and access a wealth of resources. In order to understand how data communication and networking work, it is important to have a basic understanding of the concepts involved.
Data communication is the transfer of data from one device to another. This can be done over a variety of media, including copper wire, fiber optic cable, and wireless signals. The data is typically sent in the form of packets, which are small blocks of data that are sent individually. The packets are then reassembled at the receiving device.
Networking is the process of connecting devices together so that they can communicate with each other. This can be done using a variety of technologies, including Ethernet, Wi-Fi, and Bluetooth. Once devices are connected to a network, they can share data and resources with each other.
